Seat

Abstract

A seat has a base, two seat cushions disposed above the base, and two supporting members mounted on the seat cushions and connected to the base. Each one of the supporting members has multiple supporting elements. Each one of the supporting elements has a guiding rod and a spring. The guiding rod is mounted on the base and is screwed into a corresponding one of the seat cushions. The spring is disposed around the guiding rod. Two ends of the spring abut against the base and the corresponding one of the two seat cushions. In use, the spring can generate different degrees of compression and provide different degrees of supporting force. Deviation of the spring is limited by the guiding rod to avoid excess of the deviation and ensure sufficient support. The seat has both the support and the cushioning performance to improve sitting comfort.

What is claimed is: 
     
       1. A seat comprising:
 a base having multiple through holes formed through the base; 
 two seat cushions disposed above the base, and laterally arranged; each one of the seat cushions having
 a front half section; 
 a rear half section; 
 a board disposed above the base; 
 a cushioning body mounted on a top surface of the board; and 
 a frame structure mounted on a bottom surface of the board, and having a cushioning frame and multiple threaded holes formed on a bottom surface of the cushioning frame; and 
 
 two supporting members, each one of the two supporting members mounted on the frame structure of a corresponding one of the two seat cushions, connected to the base, and having
 multiple supporting elements respectively located at the front half section and the rear half section of the corresponding one of the two seat cushions, and each one of the supporting elements having
 a guiding rod mounted on the base and having
 a head located on a bottom surface of the base, wherein an outer diameter of the head is larger than a diameter of a corresponding one of the through holes; and 
 a shank formed on the head, movably inserted through the corresponding one of the through holes, screwed into the frame structure of the corresponding one of the two seat cushions, and having an outer threaded portion formed around an outer surface of a top portion of the shank, wherein the outer threaded portion is screwed into a corresponding one of the threaded holes; and 
 
 a spring disposed around the shank of the guiding rod, and two ends of the spring respectively abutting against the base and the frame structure of the corresponding one of the two seat cushions. 
 
 
 
     
     
       2. The seat as claimed in  claim 1 , wherein each one of the supporting elements has a washer, and the washer is mounted on a top surface of the head of the guiding rod and is disposed around the shank. 
     
     
       3. The seat as claimed in  claim 2 , wherein the guiding rod of each one of the supporting elements has a tool hole formed on a bottom surface of the head. 
     
     
       4. The seat as claimed in  claim 2 , wherein a number of the supporting elements in each one of the two supporting members is four; two of the four supporting elements are disposed on the front half section of the corresponding one of the two seat cushions and are laterally arranged; the other two of the four supporting elements are disposed on the rear half section of the corresponding one of the two seat cushions and are laterally arranged. 
     
     
       5. The seat as claimed in  claim 4 , wherein the cushioning body of each one of the two seat cushions has a covering cloth, and the covering cloth is fixedly mounted on the board. 
     
     
       6. The seat as claimed in  claim 2 , wherein the cushioning body of each one of the two seat cushions has a covering cloth, and the covering cloth is fixedly mounted on the board. 
     
     
       7. The seat as claimed in  claim 1 , wherein a number of the supporting elements in each one of the two supporting members is four; two of the four supporting elements are disposed on the front half section of the corresponding one of the two seat cushions and are laterally arranged; the other two of the four supporting elements are disposed on the rear half section of the corresponding one of the two seat cushions and are laterally arranged. 
     
     
       8. The seat as claimed in  claim 7 , wherein the cushioning body of each one of the two seat cushions has a covering cloth, and the covering cloth is fixedly mounted on the board. 
     
     
       9. The seat as claimed in  claim 1 , wherein the cushioning body of each one of the two seat cushions has a covering cloth, and the covering cloth is fixedly mounted on the board. 
     
     
       10. The seat as claimed in  claim 1 , wherein the guiding rod of each one of the supporting elements has a tool hole formed on a bottom surface of the head.
